Inker
The inker (also sometimes credited as the finisher or embellisher) is one of the two line artists in traditional comic book production.
The penciller creates a drawing, the inker outlines, interprets, finalizes, retraces this drawing by using a pen or a brush. Inking was necessary in the traditional printing process as presses could not reproduce pencilled drawings. "Inking" of text is usually handled by another specialist, the letterer, the application of colors by the colorist.
As the last hand in the production chain before the colorist, the inker has the final word on the look of the page, and can help control a story's mood, pace, and readability. A good inker can salvage shaky pencils, while a bad one can obliterate great draftsmanship and/or muddy good storytelling.
